This invention relates to an improved cartridge wad suitable for shotgunshells, and has for its particular object the rovision of a wad for ashell which is adapte to operate eificiently in arms such as a shotgun.

It is desirable in constructing shotgun shells to secure the greatestpossible muzzle velocity of the shot, as this not only makes the shotcarry farther, but provides a more even and uniform pattern.

This high muzzle velocity of the shot depends to a great extent on theefiiciency of the wad which is placed between the powder or charge andthe shot. To be entirely etlicient a wad should be so impervious to thegases resulting from the explosion of the charge that the gases do notleak through it, and so strong that it is not broken, cracked ormutilated by the explosion and discharges from the muzzle as one piece.

This invention is predicated upon the discovery that the fibers of sugarcane bagasse are suitable for the fabrication of wadding. When thesefibers are compressed together into a completed wad the entwining orassociation of the fibers is such that the gases resulting from theexplosion are appropriately checked and held in back of the-wad, and yetthe wad is sufficiently resilient to accommodate itself to the bore ofthe gun and be discharged as one piece driving out the shot ahead of itat the maximum velocity permitted by the size of the charge.

The figure of the drawing is a side elevation of a shotgun shell, aportion thereof being broken away for more fully illustrating the partsof the shell.

It will be apparent that the wads of this invention may be utilized inany small arm cartridge or ammunition. A shotgun shell has beendisclosed as a form of ammunition to which application of this inventionis readily made, and in which the arrangement of the wads is exemplaryof the common arrangement. I

The cartridge case or shell proper is indicated at 1, and is usuallyapaper product. A metal cap 2 encloses the rear end of the shell andsupports the percussion pin or caprelative to the powder. The powder isgenerally indicated at 3, the wads at 4, the shot at 5, and the endclosure disc at .6, the disc being held in place by the inwardlyclinched end 7 of the case 1. Any number of wads may be used, dependingon the amounts of powder and shot used.

Hereinafter the description will be entirely related to one of theimproved wads which is placed between the powder and the shot for thepurpose of segregating the powder and shot and for other purposes whichwill be explained in detail hereinafter.

In making cartridge wadding of the nature described, the bagasse fibersare purified, that is, all gummy'material is removed from them, afterwhich they are formed into a sheet of appropriate thickness for the wad.The fibers may be appropriately secured together by a felting operationor of a suitable adhesive, such as relatively flexible glue or by both.The individual wads are then cut from the sheets so fabricated as bydyeing operations. On the other hand, the cartridge wads may befabricated by pressing the bagasse fibers together into individual moldsin combination with a suitable adhesive of the nature described.

it is considered preferable, however, to choose a binding material forthe fibers which is likewise a water proofing material. One suitablebinder is parafiin wax. Another suitable binder of this nature is madefrom a polymerized oil, such as China-wood oil or Perilla oil, or asuitable gum or resin, after which the wads may be dipped in parafiin tolubricate their passage through the gun barrel. A suitable wad may bemade from bagasse fibers and 30% China-wood oil (by 1. A wad forcartridges, comprising, an
